TL;DR

Django starts with the root URL configuration and tests URL patterns in order until the first pattern matches. Captured values are passed to the selected view, and include() delegates a prefix to another URL configuration. Naming a route lets code call reverse() or use the URL template tag instead of hard-coding a path. Namespaces prevent collisions when different apps use the same route name.

Overview
Django routing maps one incoming path to one view and gives code a stable way to build links back.

Optional upgrade with examples, trade-offs, and sharper phrasing.
Order matters because a broad pattern can shadow a more specific one. I keep app URLs close to the feature, use stable names as the internal linking contract, and reserve route parameters for resource identity rather than mixing them with unbounded search criteria. Reversing URLs also makes refactoring safer, but changing names can still break templates, redirects, tests, and external integrations.
